Acute Peritoneal Dialysis System for Neonates with Acute Kidney Injury Requiring Renal Replacement Therapy: A Case Series.

BACKGROUND

Acute kidney injury (AKI) is common in critically ill neonates, and peritoneal dialysis (PD) can be a lifesaving option. In China, however, much of the equipment for PD in neonates is not available. We describe results with a novel system for PD, which has been developed locally to improve access to therapy and care for critically ill neonates requiring PD in China.

METHODS

The system comprises a 14-gauge single-lumen central venous catheter serving as a PD catheter, inserted by Seldinger technique, with an adapted twin bag PD system. Ten neonates with AKI were treated using the novel PD system.

RESULTS

The 10 patients ranged in age from 1 day to 22 days, with bodyweights between 700 g and 3,300 g. Average time to renal function recovery was between 14 and 96 hours. Complications related to the novel PD system included leak ( = 1), catheter displacement ( = 1), and catheter obstruction ( = 1). There were no complications related to insertion, no cases of peritonitis or exit-site infection, and no subsequent hernias. A comparison of costs indicated that the novel PD system is less expensive than conventional systems involving open insertion of Tenckhoff catheters.

CONCLUSIONS

Peritoneal dialysis using the novel PD system is simple, safe, and effective for suitable neonates with AKI in China.
